The Toshiba SD-M1802 with the latest Nero CDSpeed version can measure (scan) DVD recordable and re-writable media. Whats rather interesting is that the drive with a patched firmware can read DVD±R/RW up to 16X

For our tests we used a first test disc scanned at 4X, 6X, 8X , 12X, 16X, the average scanning interval is 3.50~3.70ECC (according to the used reading speed). The SD-M1802 drive can report PI and PIF error rates.
